Product details
Overview
DG419CJ from Maxim Integrated is a precision SPDT analog switch with guaranteed 3Ω max on-resistance matching and 4Ω max on-resistance flatness over signal range, operating from ±4.5V to ±20V or +10V to +30V supplies, used in audio routing, test equipment, and battery-operated systems requiring rail-to-rail signal handling and low charge injection (10pC max).
For engineers reviewing the DG419CJ datasheet, DG419CJ pinout, DG419CJ application, or DG419CJ equivalent, key selection criteria include bipolar/single-supply flexibility, sub-175ns turn-on time, <5nA off-leakage at +85°C, ESD tolerance ≥2000V, and compatibility with TTL/CMOS logic levels.
Technical Context
The DG419CJ implements a monolithic CMOS SPDT architecture with one normally closed (S1) and one normally open (S2) channel, controlled by a single logic input (IN). Its silicon-gate 44V process enables rail-to-rail analog signal switching across ±20V or +30V ranges without degradation in RDS(ON) flatness.
Switching behavior follows break-before-make timing (≤13ns), with guaranteed low charge injection (≤10pC) and off-isolation rejection ratio of 68dB at 1MHz - critical for sample-and-hold accuracy and crosstalk-sensitive audio routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 35Ω max - ensures minimal signal attenuation in precision analog paths |
| ΔRDS(ON) | 3Ω max - guarantees matched gain/attenuation between S1 and S2 channels |
| RFLAT(ON) | 4Ω max - maintains consistent on-resistance across full ±15.5V analog range |
| tON/tOFF | <175ns / <145ns - supports high-speed multiplexing in test and comms systems |
| Charge Injection | 10pC max - limits voltage glitch in sample-and-hold and ADC front-ends |
| IOFF @ +85°C | <5nA - preserves signal integrity in high-impedance sensor interfaces |
| ESD Tolerance | 2000V min (HBM, Method 3015.7) - enables robust handling in manufacturing and field use |
Pinout & Package
Package: 8-pin plastic DIP (0.300" wide), RoHS-compliant, operating temperature range 0°C to +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 (Source 1) | Normally closed analog path - connects to D when IN = 0 |
| 2 | S2 (Source 2) | Normally open analog path - connects to D when IN = 1 |
| 3 | GND | Logic ground reference for VL and digital inputs |
| 4 | V+ | Analog positive supply - sets upper rail for bidirectional signal handling |
| 5 | VL | Logic supply - set to +5V for TTL compatibility or tied to V+ for CMOS |
| 6 | IN | Active-high digital control input - drives internal switch matrix |
| 7 | V- | Analog negative supply - defines lower rail; connect to 0V for single-supply operation |
| 8 | D (Drain) | Common analog I/O terminal - shared output/input for both S1 and S2 |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RDS(ON) match | 3Ω max between S1/S2 - eliminates gain mismatch in differential or dual-path designs |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - enables full dynamic range utilization in ±15V systems |
| Bipolar or single-supply operation | ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal PCBs |
| TTL/CMOS logic compatibility | VL pin configurable for 5V or V+ - eliminates level-shifter requirements in microcontroller interfaces |
| Low power consumption | 35µW max - extends battery life in portable test and guidance equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRZ | Higher RDS(ON) (1.3Ω typ), but wider temp range (−40°C to +125°C); requires external logic level translation for 3.3V control | Better suited for automotive or industrial environments requiring extended temperature operation | Select ADG1419BRZ if system operates beyond +70°C or demands sub-2Ω on-resistance at cost of higher supply voltage sensitivity |
| TS5A23157DCKR | Lower voltage rating (5.5V max), CMOS-only design, no bipolar support; 0.9Ω RDS(ON), but only ±3.3V analog range | Targeted at low-voltage portable electronics (e.g., smartphones, wearables), not high-voltage test or audio systems | Choose TS5A23157DCKR only for 3.3V single-supply applications where ±15V operation is unnecessary |
Compared with DG419CJ, ADG1419BRZ offers superior temperature range and lower on-resistance but lacks native bipolar supply support and requires level-shifting, while TS5A23157DCKR delivers ultra-low RDS(ON) at the expense of voltage headroom and thermal capability - making DG419CJ the optimal choice for general-purpose ±15V precision switching.

FAQ
What is the maximum analog signal range supported by DG419CJ?
The DG419CJ supports analog signals from V− to V+, enabling rail-to-rail operation. With bipolar ±15V supplies, the full range is ±15.5V; with single +12V supply (V− = 0V), it handles 0V to 12V. This is confirmed in Electrical Characteristics tables for both dual- and single-supply conditions, and validated by Typical Operating Characteristics graphs DG417-03 and DG417-04.
Does DG419CJ require external level-shifting when driven by a 3.3V microcontroller?
No - DG419CJ does not require external level-shifting when driven by a 3.3V microcontroller, provided VL is tied to V+ (for CMOS compatibility) or configured at 3.3V. The device accepts logic inputs from 0.8V (VIL) to 2.4V (VIH) with VL = 5V, and its input thresholds scale with VL. Direct 3.3V drive is feasible if VL = 3.3V and V+ ≥ 3.3V, per the Logic Input Current specifications in the datasheet.
What is the guaranteed on-resistance matching between S1 and S2 channels in DG419CJ?
The DG419CJ guarantees ΔRDS(ON) ≤ 3Ω max between its S1 and S2 channels over the full operating temperature range (0°C to +70°C) and signal range, as explicitly stated in the "New Features" section and verified in the Electrical Characteristics table under "On-Resistance Match Between Channels (Note 4)".
Can DG419CJ operate with unbalanced supplies such as +24V and −5V?
Yes - DG419CJ can operate with unbalanced supplies like +24V and −5V, as confirmed in the Applications Information section: "all device types can operate with unbalanced supplies, such as +24V and −5V." The absolute maximum rating specifies V+ − V− ≤ 44V, and the analog signal range remains V− to V+, so +24V/−5V yields a usable −5V to +24V range.
Is DG419CJ pin-compatible with older DG419 variants like DG419DJ?
Yes - DG419CJ is pin-compatible with DG419DJ and other DG419 variants (CY, C/D, DK, AK) in the same package type (8-pin DIP or SO). All share identical pinout, function mapping, and electrical interface per the Pin Description table and Top View diagrams; only temperature range and screening differ (CJ = 0°C to +70°C, DJ = −40°C to +85°C).
